bug#4806: 23.1.50; Emacs compile runs forever at ucs-normalize.el with current HEAD

[Tassilo Horn]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When I try to compile the current CVS HEAD, the byte compilation runs
forever at

  ../src/emacs -batch --no-site-file --multibyte -f batch-byte-compile \
  
/var/tmp/portage/app-editors/emacs-cvs-23.1.9999-r1/work/emacs/lisp/international/ucs-normalize.el

This is a clean checkout.

When I try to byte-compile this file with the currently installed emacs
version instead of the dumped one, it works.  So the problem seems to be
somewhere in the byte compiler and not in ucs-normalize.el.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1.50/etc/DEBUG for instructions.
